3 Installation
a
Alignment of car adapter (MBT 1000/2000/3000)
Place the adapter at the collar of the gearbox flange. Then align the
adapter horizontally using a spirit level and tighten it.
b
Alignment of force sensor (all MBT models)
During installation, the force sensor must be aligned using a spirit level. To
do this, load the line of force with approx. 200 N to eliminate play from the
structure.
Under this load, the force sensor can be aligned free of play by moving the
support frame.
8 BA020001_003-en
c
Position and orientation of support plate
e.g. MBT 1000/4000/5000/6000/7000 e.g. MBT 2000/3000/(7000
old)
e.g. MBT 2000/3000/all MBTs MBT 2000/3000 opposite direction
d
Using the hook unit (MBT 4000/5000/6000/7000)
• Connect the calibration arm with
the fork.
• Attach the spacer for pushing
down the sensor roller.
e
Note minimum screw-in depth!
The minimum screw-in depth is marked in red on forks and adapters.
BA020001_003-en 9
f Using the support plates (MBT 2000/3000 opposite direction)
The support plates can be screwed to the feet of the MJV II. This may be
necessary in case the MJV II cannot be positioned suitably on the MBT
frame or cannot be adjusted as shown due to an unfavourable contact
surface (e.g. caused by adjacent objects).
g
Using the calibration supports (MBT 5000)
The calibration supports are stored in the motor compartment of the
MBT 5000 and are screwed to the test stand frame for calibration.

by using the pressure spindle.
